Acquired pulmonary stenosis and pulmonary artery compression

Acquired pulmonary stenosis and pulmonary artery compression.

Acquired Pulmonary Stenosis

Acquired pulmonary stenosis refers to narrowing of the right ventricular outflow tract or main pulmonary artery which has developed after birth. It may arise from external pressure or from an intrinsic pathological process, and is generally regarded as a rare condition because few cases have been reported. Our experience, however, suggests that it is probably not as rare as previously believed ...

Acquired pulmonary stenosis due to compression by a bronchiogenic cyst.

A case of pulmonary stenosis due to extrinsic compression of the pulmonary artery and right ventricular infundibulum is reported. It is believed that this is the first such case recorded in the English literature where the cause of the compression was a bronchiogenic cyst. Pulmonary stenosis due to compression of the right ventricular outflow tract by an extrinsic mass is an uncommon but well-d...

Pulmonary artery compression by a bronchogenic cyst simulating congenital pulmonary artery stenosis.

DS, a 21-year-old woman admitted to the hospital because of dyspnea and pleuritic chest pain for 5 days, had the diagnosis of congenital right PA stenosis since age 6 years, when a systolic precordial murmur was noted. Cardiac catheterization in childhood showed isolated mild right PA stenosis; the mean pressure in the pulmonary trunk was 30 mm Hg, and the mean right PA pressure was 15 mm Hg. S...
